I am trying to show a reveal.js presentation full screen from a JHipster single page app. The reveal.js example below works fine inside JHipster, it's just not full screen. It can be made full screen by creating a second page, but given JHipster's design as a single page app things get messy with grunt and the production profile. I've also tried hiding the app menu bar and footer div elements but the reveal presentation still has padding around it. Ideally a full-screen view can configured.
Simple Reveal slide
<div ng-cloak>
<div class="reveal">
<div class="slides">
<section data-background="#faebd7">
<h1>FULL SCREEN SLIDE</h1>
</section>
</div>
</div>
</div>
A second page is the way to go and below is a way to by-pass optimizations made by JHipster's production build.
JHipster's production build only optimizes files under src/main/webapp/scripts and src/main/webapp/assets directories. So, put your presentation files including revealjs under another folder (e.g. src/main/webapp/slides) and use a simple link from your app to load the presentation.
This is what is done for swagger-ui under src/main/webapp/swagger-ui
I solved the problem while keeping it a single page app. Previously I tried hiding elements of the page that prevented full-screen, but padding on the main div container was preventing full screen. The solution was to create a second ui-view div designed for full screen and hide all other div elements.
Solution:
1. Add "hidewhenfullscreen" class to the elements to hide.
2. Use javascript to show/hide elements
3. Add a second fullpage ui-view designed for full screen
4. Reference the fullpage ui-view from the controller
index.html
<div ng-show="{{ENV === 'dev'}}" class="development hidewhenfullscreen" ng-cloak=""></div>
<div ui-view="navbar" ng-cloak="" class="hidewhenfullscreen"></div>
<div class="container hidewhenfullscreen">
<div class="well" ui-view="content"></div>
<div class="footer">
<p translate="footer">This is your footer</p>
</div>
</div>
JavaScript to show/hide elements
<script>
hide(document.querySelectorAll('.hidewhenfullscreen'));
function hide (elements) {
elements = elements.length ? elements : [elements];
for (var index = 0; index < elements.length; index++) {
elements[index].style.display = 'none';
}
}
function show (elements) {
elements = elements.length ? elements : [elements];
for (var index = 0; index < elements.length; index++) {
elements[index].style.display = 'block';
}
}
</script>
JavaScript controller
.state('show', {
parent: '',
url: '/show/{presentationName}',
data: {
authorities: [], // none, wide open
pageTitle: 'page title'
},
views: {
'fullpage#': {
templateUrl: 'scripts/show/show.html',
controller: 'ShowController'
}
}
})
The page has a single small "Home" href that calls the show function. This way the user can go back and forth between the full-screen Reveal presentation and the standard jHipster view.
show.html
<div ng-show="{{ENV === 'dev'}}" class="development"></div>
<div class="miniMenu" id="miniMenu" ng-cloak="">
Home
</div>
<div class="reveal">
<div class="slides">
<section data-background={{getBackgroundURI($index)}} ng-repeat="slide in slides track by $index">
<div ng-bind-html="getContent($index)"></div>
</section>
</div>
</div>
For completeness, creating a second page can work but I don't think it is worth the added complexity. A two-page solution worked fine in the development profile, but the production profile had issues with caching shared css files, js files and fonts. With time and energy, I am sure the proper grunt configuration can be made to work, although the idea seems to counter the single page design concept. While in Rome, do as the Romans do.

I have a webgrid with a hyperlink column and upon clicking that link it should open a modal popup I have a modal named #examplemodal in a partial view named"GetDetails". Below I try to open the modal from a controller action method that returns partial view.
#Html.ActionLink("OrderNumber","GetDetails","Home",
new{id = item.ID}, new{data_target="#exampleModal", data_toggle="modal", #class="modal-backdrop"});
When I click on the link with Ordernumber screen blacks out and I dont see the grid at all. Any pointers on where I am doing a mistake. I am using asp.Net mvc5 and bootstrap v4.3.1
I think your concept is totally wrong. I assume you want to display the order details in a modal? And since you have a method to return a partial view for that already, you want to load that order details content into modal whenever the user clicks the hyperlink column?
If that's the case, bootstrap modal is not the right tool for you. It's designed to load static content. If you want to load dynamic content, i.e., order details for different order numbers, you should look into a concept called iframe, and libraries like Fancybox, etc.
Here's what I would do:
1.Define a modal layout
Because you want to display the partial view on a modal, you generally don't want to have things like sidebar, top navigation, etc, from your site layout. Hence I will define a layout for modals.
<!-- _PopupLayout.cshtml -->
<!DOCTYPE html>
<html>
<head>
<!-- Required meta tags -->
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no" />
<!-- All your necessary styles, meta data, etc -->
<title>...</title>
#RenderSection("css", required: false)
</head>
<body>
<main class="container-fluid">
#RenderBody()
</main>
<!-- All your necessary javascripts -->
#RenderSection("scripts", required: false)
</body>
</html>
2.Return views that use _PopupLayout
I know you've created partial views. But regular view is fine. In fact, it's better because you can setup the layout the regular view uses, as well as the view models for that.
Because you want this view to look like a bootstrap modal, you should construct your view using bootstrap modal structure.
#model ...
#{
ViewData["Title"] = "Order Details";
Layout = "~/Views/Shared/_PopupLayout.cshtml";
}
<div class="modal-header">
<h5 class="modal-title">Order Details</h5>
</div>
<div class="modal-body">
...
</div>
3.Write JavaScript to trigger FancyBox on link clicking
You can use a custom css class for the selector for all links you want to load the iframe from. In my case I call it .popup-fancy. You can also define multiple classes for popping up different sizes of modals/fancybox modals.
$(function() {
$().fancybox({
selector: 'a.popup-fancy',
defaultType: 'iframe',
baseClass: 'fancybox-md',
iframe: {
preload: false
},
arrows: false,
infobar: false,
smallBtn: true
});
$().fancybox({
selector: 'a.popup-fancy-lg',
defaultType: 'iframe',
baseClass: 'fancybox-lg',
iframe: {
preload: false
},
arrows: false,
infobar: false,
smallBtn: true
});
$().fancybox({
selector: 'a.popup-fancy-xl',
defaultType: 'iframe',
baseClass: 'fancybox-xl',
iframe: {
preload: false
},
arrows: false,
infobar: false,
smallBtn: true
});
});
See how it sets the default type to iframe? You can find those configuration options from Fancybox documentation. Not to forgot those 3 base classes styles (I'm using Sass):
.fancybox-md {
.fancybox-content {
max-width: 36.75rem;
}
}
.fancybox-lg {
.fancybox-content {
max-width: 65.625rem;
}
}
.fancybox-xl {
.fancybox-content {
max-width: 78.75rem;
}
}
4.Create links to open modal
Now you can create links with any of those fancybox trigger classes:
<a href="#Url.Action("details", "order", new { area = "", id = item.Id })"
class="popup-fancy">
See Order Details
</a>
I assume you have the order controller and details action method all setup to return a view that uses the _PopupLayout, then when the user clicks on the link, instead of the regular redirect to the page using standard layout, the page content should be loaded into the fancybox modal.
For example:
If you can only use bootstrap modal??
In that case, you will have to create a modal template (probably in the layout so that it can be called anywhere) with an iframe inside. And then on link clicked, you use javascript to set the source of the iframe and manually popup the modal.
Sample of modal template
<div id="fancy-modal" class="modal fade" tabindex="-1" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<iframe src="" frameborder="0"></iframe>
</div>
</div>
</div>
Then on the page where you generate links, instead to generate actual links, you will have to generate the modal triggers:
<a href="#" class="fancy-modal-trigger"
data-iframe-src="#Url.Action("details", "order", new { area = "", id = item.Id })">
See Order Details
</a>
See here you put the actual link to your view on a data-attribute instead of href, because you don't want the link to actually navigate to the destination.
$(function() {
$('a.fancy-modal-trigger').click(function() {
let iframeSrc = $(this).data('iframe-src'),
$fancyModal = $('#fancy-modal');
$fancyModal.find('iframe').prop('src', iframeSrc);
$fancyModal.modal('show');
return false;
});
});
DISCLAIM: this is not yet tested.
Right now, I'm trying to make a website that shows recent news posts which is supplied my NodeJS API.
I've tried the following:
HTML
<div id="news" class="media" v-for="item in posts">
<div>
<h4 class="media-heading">{{item.title}}</h4>
<p>{{item.msg}}</p>
</div>
</div>
JavaScript
const news = new Vue({
el: '#news',
data: {
posts: [
{title: 'My First News post', msg: 'This is your fist news!'},
{title: 'Cakes are great food', msg: 'Yummy Yummy Yummy'},
{title: 'How to learnVueJS', msg: 'Start Learning!'},
]
}
})
Apparently, the above didn't work because Vue can't render multiple root elements.
I've looked up the VueJS's official manual and couldn't come up with a solution.
After googling a while, I've understood that it was impossible to render multiple root element, however, I yet to have been able to come up with a solution.
The simplest way I've found of adding multiple root elements is to add a single <div> wrapper element and make it disappear with some CSS magic for the purposes of rendering.
For this we can use the "display: contents" CSS property. The effect is that it makes the container disappear, making the child elements children of the element the next level up in the DOM.
Therefore, in your Vue component template you can have something like this:
<template>
<div style="display: contents"> <!-- my wrapper div is rendered invisible -->
<tr>...</tr>
<tr>...</tr>
<tr>...</tr>
</div>
</template>
I can now use my component without the browser messing up formatting because the wrapping <div> root element will be ignored by the browser for display purposes:
<table>
<my-component></my-component> <!-- the wrapping div will be ignored -->
</table>
Note however, that although this should work in most browsers, you may want to check here to make sure it can handle your target browser.
You can have multiple root elements (or components) using render functions
A simple example is having a component which renders multiple <li> elements:
<template>
<li>Item</li>
<li>Item2</li>
... etc
</template>
However the above will throw an error. To solve this error the above template can be converted to:
export default {
functional: true,
render(createElement) {
return [
createElement('li', 'Item'),
createElement('li', 'Item2'),
]
}
}
But again as you probably noticed this can get very tedious if for example you want to display 50 li items. So, eventually, to dynamically display elements you can do:
export default {
functional: true,
props: ['listItems'], //this is an array of `<li>` names (e.g. ['Item', 'Item2'])
render(createElement, { props }) {
return props.listItems.map(name => {
return createElement('li', name)
})
}
}
INFO in those examples i have used the property functional: true but it is not required of course to use "render functions". Please consider learning more about functional componentshere
Define a custom directive:
Vue.directive('fragments', {
inserted: function(el) {
const children = Array.from(el.children)
const parent = el.parentElement
children.forEach((item) => { parent.appendChild(item) })
parent.removeChild(el)
}
});
then you can use it in root element of a component
<div v-fragments>
<tr v-for="post in posts">...</tr>
</div>
The root element will not be rendered in DOM, which is especially effective when rendering table.
Vue requires that there be a single root node. However, try changing your html to this:
<div id="news" >
<div class="media" v-for="item in posts">
<h4 class="media-heading">{{item.title}}</h4>
<p>{{item.msg}}</p>
</div>
</div>
This change allows for a single root node id="news" and yet still allows for rendering the lists of recent posts.
In Vue 3, this is supported as you were trying:
In 3.x, components now can have multiple root nodes! However, this does require developers to explicitly define where attributes should be distributed.
<!-- Layout.vue -->
<template>
<header>...</header>
<main v-bind="$attrs">...</main>
<footer>...</footer>
</template>
Multiple root elements are not supported by Vue (which caused by your v-for directive, beacause it may render more than 1 elements). And is also very simple to solve, just wrap your HTML into another Element will do.
For example:
<div id="app">
<!-- your HTML code -->
</div>
and the js:
var app = new Vue({
el: '#app', // it must be a single root!
// ...
})
I'm using slick carousel, and once a div is active I want to open the corresponding description.
Problem I'm having is with this code:
if ($('div').hasClass('active')) {
var title = $(this).attr('title');
$('ul li').removeClass('open');
$(title).addClass('open');
}
What I'm trying to achieve:
Once a div gets class 'active', I want to take its title value, and use it as a id link to list element I want to display(add class to).
Here is a FIDDLE.
Use event handling, not class monitoring.
The slick carousel API has events for this, I believe you want to use the afterChange event to act on the active element after it has been made visible.
Check out the docs and examples, especially the section titled "Events" on Slick page: http://kenwheeler.github.io/slick/
And I think you don't want to use title attribute for this because that is for tooltips. I recommend data-* attributes instead. And element IDs should generally start with a letter and not a number (was required in HTML4 and makes life easier when mapping IDs to JavaScript variables; though if you are using HTML5 I think this requirement is no longer in effect).
HTML
<div id="carousel">
<div data-content-id="content1">
Selector 1 </div>
<div data-content-id="content2">
Selector 2 </div>
<div data-content-id="content3">
Selector 3 </div>
</div>
<ul class="content">
<li id="content1">Content 1</li>
<li id="content2">Content 2</li>
<li id="content3">Content 3</li>
</ul>
JavaScript
$('#carousel').on('afterChange', function(event, slick, currentSlide) {
// get the associated content id
var contentId = $(slick.$slides.get(currentSlide)).data("content-id");
if(contentId && contentId.length)
{
var $content = $("#" + contentId);
$(".content>li").removeClass("open"); // hide other content
$content.addClass("open"); // show target content, or whatever...
}
});
I have found a solution:
$('.slider').on('afterChange', function(event, slick, currentSlide, nextSlide){
var contentId= $(slick.$slides.get(currentSlide)).data('content');
if(contentId)
{
$(".content li").removeClass('open');
$('#' + contentId).addClass('open');
}
});
Working fiddle
I'm new to Orchard and have watched both the Pluralsight "Orchard Fundamentals" and "Advanced Orchard" tutorials. Its a great platform, but I'm having a hard time wrapping my head around a couple of things.
I'd like to create a blog showcase banner on the home page only that rotates blog posts on the site. I have the HTML sliced up and functioning on an HTML template. The banner looks like this:
http://arerra.com/news-slideshow.jpg
So far I have done the following:
I've created a Blog called "Articles" and have placed a single post in there for testing.
Added a Layer called "ArticleList" where I have placed a Widget for "Recent Blog Posts"
I've created a custom layout for the home page called "Layout-Url-HomePage.cshtml" in my theme.
In my Theme "Views" folder, I have created a file called "Widget.Wrapper.cshtml" with only #Display(Model.Child) in it to remove the <article><header/><footer /><article> tags globally from the widgets.
Added a file in "Views > Parts > Blogs.RecentBlogPosts.cshtml" to control the layout of my shape. The code is the following:
#using Orchard.ContentManagement;
#{
IEnumerable<object> blogPosts = Model.ContentItems.ContentItems;
}
#if (blogPosts != null) {
<div class="container news-slider">
<ul class="slide-images">
#foreach (dynamic post in blogPosts) {
string title = post.Title;
ContentItem item = post.ContentItem;
<img src="/Themes/MountainWestHoops/Content/img/placeholder-700x380.jpg" alt="#title" class="active" />
}
</ul>
#foreach (dynamic post in blogPosts) {
string title = post.Title;
string body = post.Body;
ContentItem item = post.ContentItem;
<div class="featured-story threeD active">
<h1>#title</h1>
<p>#body #Html.ItemDisplayLink("READ MORE", item)</p>
</div>
}
<aside>
<ul class="tabs">
#foreach (dynamic post in blogPosts) {
string title = post.Title;
string url = post.Url;
ContentItem item = post.ContentItem;
<li><h3>#title</h3></li>
}
</ul>
<div class="ad-three-day-trial">
<img src="/Themes/Content/img/placeholder-260x190.gif" />
</div>
</aside>
</div>
}
My HTML is rendering properly, but none of the values that I have specified are showing up.
I am using the "Shape Tracer" module to see what template is being used. What is funny, is that the #Html.ItemDisplayLink("READ MORE", item) is rendering the article's URL, and if I replace the "READ MORE" with the string title, the title renders properly.
What am I doing wrong here that is causing strings to not display? Am I missing a larger point and misunderstanding the fundamentals? The tutorials seems to say that you can simply move around parts, but in this case, I need to have very specific markup for this slider to work.
Seems like your source was http://weblogs.asp.net/bleroy/archive/2011/03/27/taking-over-list-rendering-in-orchard.aspx
That is a rather old post, and the way the title is handled has changed since then.
The DisplayLink works because the only correct property here is post.ContentItem, which is what that API takes. post.Title and post.Body on the other hand are very likely null, which is why you see nothing. To access the title, you can use post.ContentItem.TitlePart.Title and to get the body, post.ContentItem.BodyPart.Text.
I am very new to Orchard.
I have created a new theme, based on the Minty theme. The only real change is the layout, where I have adapted the html from an existing asp.net masterpage to match the orchard style razor layout.cshtml. I have experience with MVC and razor, so no problem on that side... unless I have missed something vital.
The problem is the login page. Clicking the sign in link takes me to the correct url without errors, but not login form gets rendered. I have checked that this is the case by Inspecting Element in google chrome.
I am aware that setting up widgets, etc, I can make content appear. However, I can't find how the login form gets inserted when the login url gets requested. I presume it uses the Orchard.Users module, but not sure how. Does it need a specific zone? I can't see why, but see how else.
As a result, I can't solve my problem...
Any pointers?
Any books or other learning media?
The code for my layout.cshtml is:
#functions {
// To support the layout classifaction below. Implementing as a razor function because we can, could otherwise be a Func<string[], string, string> in the code block following.
string CalcuClassify(string[] zoneNames, string classNamePrefix) {
var zoneCounter = 0;
var zoneNumsFilled = string.Join("", zoneNames.Select(zoneName => { ++zoneCounter; return Model[zoneName] != null ? zoneCounter.ToString() : "";}).ToArray());
return HasText(zoneNumsFilled) ? classNamePrefix + zoneNumsFilled : "";
}

ADDENDUM:
See Bertrand Le Roy's answer below. The Orchard.Users module requires a Content zone with a Capital C. That instantly cured the problem.
I added this as Bertrand's response was tentative, and I wanted to reinforce that the problem was the name of the zone.
In Orchard.Users, look for Controllers/AccountController.cs. In there, there is a LogOn action. It creates a LogOn shape that it then puts in a shape result. This then gets resolved as the Views/LogOn.cshtml template (which you can override in your theme by just dropping a file with the same name in there, for example a copy of the original that you can tweak). The LogOn template will be rendered within the theme's layout, in the Content zone. Does this answer your question?
I think the mistake you made was to name your Content zone content (notice the casing).
